SV135 Zoom Eyepiece, 1.25inch 7-21mm for Telescope, FMC 6 Element 4 Group Lens, Accessories for Planetary Moon Astronomy Observation

Bought this to save swapping out eyepieces all the time. The focal range is great, the image is clear and it's very comfortable on the eye when viewing. I think it's exceptional value for the quality of the build and image through the eyepiece, and I'm finding this is my go-to eyepiece at the moment because it's so convenient. Well worth the money.

Impresionante la nitidez de sus imágenes, merece la pena tener uno de estos oculares

Le zoom 8x24 Bondy oculaires astronomie de grande quantité.je recommande ce produit pour l astronomie.m.c

Have just started out on my hobby of amateur astronomy, so I'm no expert. I've bought a decent Celestron scope as well as a decent set of very large and heavy Celestron binoculars. Spent about £1,000 so far, including some nice Celestron eyepieces. I've sought, and been given, some excellent advice. But I've been curious about the Svbony equipment advertised on Amazon, noting that mainstream astronomy websites don't mention Svbony at all. Nevertheless, I decided to take the plunge on this 10 to 30 zoom lens. And I'm glad I did! It works beautifully and I'm extremely impressed with the images I get. So I'm going to try out some more Svbony equipment. Anyway, if you're after more of a budget eyepiece, I'd certainly recommend giving this a go.

Sympatyczny maluch. Oczywiście jak każdy zoom zabiera trochę światła, ale poza tym optycznie jest co najmniej dobry, a biorąc pod uwagę cenę, nawet bardzo dobry. Lubię w nim płynną, a nie skokową zmianę powiększenia, dobrze dobrany - ani za mały, ani za duży - opór "potencjometru", całkiem spore pole widzenia i dobrą ostrość (najlepsza przy ogniskowej circa 16 mm), mechaniczną precyzję, no i to, co w każdym zoomie - brak konieczności zmiany okularów.
